Kernrechtsfrage
Whether the bank had standing to challenge the authorization of foreign officials to attend the evidence-gathering measure.
Extrahierter Entscheid
The bank did not show that it was directly affected in its banking activity by the mutual assistance measure and therefore lacked standing.
Extrahierte Begründung
In mutual assistance, standing belongs only to persons directly subjected to the measure and with a legally protected interest. A bank ordered only to produce client documents is generally not entitled to appeal on behalf of clients or third parties.
